Abstract

A satellite receiver (200) includes a multi-channel tuner (215) for processing a plurality of different transponder signals to simultaneously provide a plurality of different bit streams (231-1, 231-2, 231-3, 231-L) from at least two of the transponder signals. The multi-channel tuner includes (a) a demultiplexer for demultiplexing a received signal representing the plurality of transponder signals into a plurality of sample signals, each transponder signal conveying a bit stream, (b) a plurality of bifurcated filters operative on the plurality of sample signals for providing a plurality of filtered signals, and (c) a discrete cosine transform element operative on the plurality of filtered signals for simultaneously providing at least two of the bitstreams.
